7 Claims. (Cl. 20-42) This invention relates to window operating mechanisms and more particularly to window hinge devices adapted to be used on awning type windows or the like.

It is an object of this invention to provide an awning type window wherein a new and novel hinge mechanism is utilized which requires no special window frame or sash structure for mounting purposes. Since no special window structure is required for mounting the operating mechanism, a considerable saving is realized from using the new and improved hinge mechanism embodied in this invention.

Another object of this invention is to provide a new and improved awning type window hinge mechanism which is simple in construction, durable, and etlicient in operation.

Still another object of this invention is to provide a new and improved window hinge mechanism that can be readily and easily mounted and operated.

A further object of this invention is to provide a new and improved awning type window operating hinge which will not tend to jam, stick, or catch, due to changing weather conditions or painting.

These and other advantages of the invention will be more clearly understood from the Vfollowing description taken in connection with the accompanying drawings and its scope will be apparent from the appended claims.

Figure lis a perspective view of a window casement having two awning type sashes mounted therein according to this invention with one being open and one being in a closed position; -Y l Figure 2 is a vertical sectional view of a window frame having an awning type window mounted therein with the novel hinge mechanism shown in an open position;

Figure 3 is a similar View, showing the operating hinge partly in section and in a closed position;

Figure 4 is a partial vertical sectional view taken along lines 2 2 of Figure 3; and

Figure 5 is a horizontal sectional view taken along lines 3-3 of Figure 3.

Referring more particularly to the accompanying drawings, in Figure l a window frame 1 has sashes 2 and 3 mounted therein by means of the operating mechanisms or hinges 4 and 5, respectively. Sash 2 and hinge 4 are shown in their open positions, while sash 3 and hinge 5 are shown in their closed position. A sliding rod device 6 or similar means may be used to hold the sash in various positions as desired. This means is shown generally and does not comprise a part of the invention.

Figure 2 shows a more detailed view of the hinge structure in an open position mounted on a window frame 10 and on an awning type window sash 11, a'nd Figure 3 shows an enlarged detailed view of the hinge structure in its closed position. The hinge mechanism has a support member mounted on window frame 10 by screws 35, 36, and 37. The support member 20 is composed of members 21 and 22, shown in detail in Figures 4 and 5 which are attached by spot welding, for example at points 43, to form support member 2l), having a track or channel 23 therein. Channel 23 extends over a substantial portion of the support member 20. From Figure 5, it is noted that member 22 of support member 20 has a flange portion which allows support member 20 to be attached to the window frame solidly without impairing or obstructing the slidable operation in channel 23. A triangular plate 25 is slidably mounted in channel 23 by bearings 26 and 27 which are inserted in holes at opposite end portions of plate 25 as shown in Figures 3 and 4. A bracket 12 adapted to be attached to window sash 11 by screws 33 and 34 is pivotally mounted at pivot 29 to the apex of triangular plate 25. A support arm or link 19 is pivotally connected by pivot 24 to the lower portion of support member 20. A bracket 18 adapted to be secured to window sash 10 by screws 30 and 32 is pivotally connected at pivot 28 to the other end of support arm 19.

Figure.4 shows a view of support member 20 partially in section. Members 21 and 22 which make up support member 20 vprovides a channel 23 in which plate 25 is free to roll up and down in by the rotatable action of bearing 26 and 27. An opening 40 leading into channel 23 Ais provided by members 21 and 22 to allow a free sliding action by plate 25 in channel 23.

With reference to Figure 3, it should be noted that support member 20 angles olf on its upper portion with respect to the plane of its main portion. This angled portion of member 20 is adapted to accommodate the triangularplate 25 when the sash is in its closed position as shown in Figure 3. As sash 10 is pushed outward, support arm 19 is pivoted by pivot 24 and moves out and away from support member 20.V Bracket 18 is also pivoted `at pivot 28 on the other end of support arm 19 to remain at right angles with Window sash 11. Simultaneouslywith thev aforesaid movement, plater 25 slides down in channel 23 and bracket 25 is pivoted at pivot 29 to force the window sash to move down and swing outward in cooperationwith arm 19 and bracket 18 as shown in Figure 2. When closing window sash 11, plate 25 moves up in channel 23Y into the angular -portion of support member 20 and arm 19 moves up and into support member 20 as shown in-Figure'3.

In Figure 5, vthe constructions of bracket 18, pivot 21, and support member 20 are shown'. *'Like support lmember 20, Abracke'tll'l is composed .of two parts, members 41 and 42. Bracket 12 also has two parts. This type of construction is advantageous in that the members may be easily assembled by spot welding and will allow the free movement required in a mechanism of this type.

The hinge structure embodied in the invention requires no special window frame or sash. These hinges may be easily mounted on all types of frames and sashes. The hinge structure is sturdy and its easy operation will not be impeded by painting or changes in weather conditions.

Since other modifications varied to lit particular operating requirements and environments will be apparent to those skilled in the art, the invention is not considered limited to the examples chosen for purposes of disclosure and covers all changes and modifications which do not constitute departures from the true spirit and scope of this invention.
